Dear VMD users,

VMD Version: 1.9.2

Problem: Error in custom vmdrc script

Problem script:
# Our colors set by name.
# The "after idle" command is because the .vmdrc is processed too early
# for colors to be set; this makes it so that it occurs after other
# stuff is properly set up.
# The dummy molecule is created because we can't set colors if no
# molecules exist.
# See
https://sites.google.com/site/akohlmey/random-hacks/vmd-initialization-scripts
after idle {
    # create dummy molecule with one atom
    set mol [mol new atoms 20]
    set sel [atomselect $mol all]
    # add items to color categories
    # Water and Hexane project

    # clean up
    $sel delete
    mol delete $mol
}

Error:
When VMD starts up it throws an application error with this message:

Unable to change color name
Unable to change color name
    while executing
"color Name "CH2" yellow"
    ("after" script)

Thank you very much,
